Four 6 Gb SAS host interface ports two per controller. Feature or PN 68Y or 68Y is a required prerequisite 32 FlashCopy instances are provided without charge when ss3512 DS is upgraded to controller firmware v7.

Feature PN 68Y is required to utilize the self encryption capability. Get a 4-terabyte USB 3. Asynchronous mirroring queues remote writes to reduce the latency, thus enabling long distance replication while increasing local system performance. Supported on dual controller systems only: IBM recommends using FlashCopy with controller firmware v7.

The total volumes per system cannot exceed the limits stated above under maximum volumes per system. The models for the storage servers are DS and DS Refer to the Chargeable section for feature numbers and part numbers: Accessibility by people with disabilities A U. You choose the configuration to match your current performance requirements and budget, and IBM offers a way to protect your investment with an upgrade path to later add the options you need.


Feature PN 68Y is a required prerequisite. FlashCopy volumes appear and function as standard storage volumes, and restoration of a FlashCopy volume is quick and easy. Upon completion of the Volume Copy process, the new volume can be mapped to any host and functions as a standard volume.

High-efficiency power supplies designed to meet power efficiency standards for reduce power consumption Small form factor 2. Supported on Model C2A only. RAID levels 0, 1, 3, 5, 6, and 10 Maximum volumes per system: The disk drives are installed at the front, as shown in the below figures.

This reduces the number of disk drives needed to meet performance and capacity demands, resulting in lower acquisition and operational expenditures.

IBM System Storage DS3512 Model C2A – hard drive array Series

Using copy-on-write technology, FlashCopy volumes preserve data in its original form even as data in the physical source volume is changed. Supported on Model E2A only. This balanced performance, combined with the ability ivm handle concurrent workloads, makes the DS a great fit for consolidation and virtualization environments. Disk drives are not included with the base model.

Act like your business depends on them by David Gewirtz. Storage by Rick Ibj Sep 13, Upgrade 81Y Host Kits: Storage Controller 2nd Type.

When installed on a DS dual controller system, both cards must be configured to run at the same link speed. Expansion Bays Form Factor. Storage by Rick Broida Oct 10, With these encryption services, FDE key management is transparent to day-to-day storage administration, ds3521 SED drives as easy to manage as traditional drives.


This model is configured with one environmental services module ESM.

Volume Copy is used with FlashCopy to create a physical copy of your data dss3512 minimal disruption to applications and production processes. Discussion threads can be closed at any time at our discretion. The difference starts with the physical drive size and extends to their speeds and storage capacities.

The DS dc-powered model requires: The following fiber optic cables can be ordered with the DS Storage Max Supported Capacity. Storage Controller Buffer Size.

For the DS DC, this feature requires controller firmware level About iStorage Networks This feature is required for both the primary and remote machines. A FlashCopy volume is the logical equivalent of the physical volume, but is created more quickly than a physical copy and with minimal disruption to applications and production processes.

Upgrade No Longer Available as of June 21, This feature provides an activation key to increase the quantity of FlashCopy images supported per physical volume from four to eight, with: In many situations, the required lengths and installation of host attachment cables will be unique to each customer’s configuration and facility specifications.
